Inman Connect Small businesses, which comprise 99.9 percent of all American enterprises, have borne the brunt of the economic downturn resulting from the coronavirus pandemic. Some 4 million of them closed their doors in 2020, and in polling undertaken by the U.S. Chamber of Commerce in December, nearly half of those owning such companies described their financial health as no better than average. New president Joe Biden has promised to address this matter as part of a sweeping $1.9 trillion COVID-19 relief bill, but that only goes so far, considering there are over 30 million small businesses in the U.S., employing nearly 60 million people.
